       4. The system of  claim 1 , wherein the cylinder includes an air valve, and wherein the air valve is a one-way air valve that has a conical shaped or duck-billed styled valve in the interior to prevent backflow or a one-way air valve that has a baffle type design. 
     
     
       5. A water filter system for a water cooler of the inverted water bottle type, comprising:
 a rod that is removably mountable in a reservoir of the water cooler under an inverted, installed water bottle, the rod aligned with a neck of the water bottle; 
 a hollow cylinder having a diameter less than the neck, an open end, and a distal end opposing the open end, the open end having an external flange at a perimeter thereof with a diameter greater than the neck, the distal end configured to removable retain a water filter, the cylinder dimensioned to accept a portion of the rod; 
 a cover having a ring-shaped base and a sidewall, the base having an inner perimeter, an outer perimeter with a diameter greater than the diameter of the flange, the sidewall extending from the base at the outer perimeter, the cover configured to receive at least the flange of the cylinder; 
 a filter that is removably connectable to the distal end of the cylinder, 
 an air valve attached to the flange and disposed in the neck when the cylinder is inserted in the neck up to the flange, wherein the cover includes an air valve throughhole between the perimeters, and when the cylinder is received in the cover and the ring-shaped base is in contact with the flange, the throughhole is aligned with the air valve; and 
 a neck sleeve that is removably attached to the neck and, when attached, extends both outwardly and away from the neck toward a body of the bottle, 
 wherein the sleeve is dimensioned and configured to receive the neck and at least a portion of the neck cover, and wherein the neck sleeve cooperates with the cylinder and the cover to provide the water tight seal, 
 wherein, when the cylinder is inserted into the neck up to the flange and the cover receives the cylinder, the cylinder and cover cooperate to: provide a water tight seal that permits only water filtered by the filter to exit the water bottle; and to receive at least a portion of the neck, and 
 wherein, when the neck is received between the cover and cylinder and the water bottle is in an installed, inserted condition, a portion of the rod extends into the hollow of the cylinder. 
 
     
     
       6. The system of  claim 5 , wherein the neck sleeve is made of a flexible material to encourage a water-tight seal between the bottle neck and the cylinder. 
     
     
       7. The system of  claim 5 , further comprising a collar that threadedly engages an exterior of the sleeve and presses a portion of the neck sleeve toward the neck. 
     
     
       8. The system of  claim 1 , wherein, when the neck is received between the cover and the cylinder, the filter is wholly disposed within the water bottle. 
     
     
       9. A water filtering system for use in a bottle type water cooler that receives an inverted water bottle, comprising:
 a base removably mountable in a reservoir of the water cooler, the base including a vertical rod extending upwardly therefrom; and 
 a cap including:
 a hollow cylinder having an open proximal end, a distal end, and an outer flange extending outwardly from a perimeter of the proximal end, the distal end configured to removable retain a water filter and permit filtered water to flow therethough, the cylinder dimensioned to be insertable into a neck of the water bottle up to the outer flange so as to position a received water filter in the bottle, and 
 a cover having a cylindrical sidewall and an inner flange with a central opening that permits the rod to extend therethough, the cover dimensioned and configured to receive the neck and the cylinder, 
 
 wherein, when the cylinder is inserted into the water bottle and the cover is fit around the cylinder such that the flanges are in contact, the filter is disposed in the bottle, the neck is disposed between the cylinder and the cover, and the cylinder and cover cooperate to provide a selective water tight seal between the neck and a filter positioning unit that permits only filtered water to flow out of the bottle into the water cooler, and 
 wherein, when the cylinder is inserted into the neck, the cover receives the cylinder, and the bottle is in the inverted, installed condition, a portion of the rod extends through the central opening and into the cylinder, via the proximal end. 
 
     
     
       10. The system of  claim 9 , wherein the outer flange has an air valve, the inner flange has an air valve throughhole and, when the flanges are in contact the air valve throughhole is aligned with the air valve. 
     
     
       11. A water filtering bottle cap, comprising:
 a hollow cylinder having an open proximal end, a distal end, and an outer flange extending outwardly from a perimeter of the proximal end, the proximal end configured to receive a portion of a stabilizing rod, the distal end having a water filter holder and configured to permit filtered water to flow therethrough, the cylinder dimensioned to be insertable into a neck of the water bottle distal end first up to the outer flange; 
 a cover having a cylindrical sidewall and an inner flange with a central opening that permits the stabilizing rod to extend therethrough, the cover fitting over the cylinder and the neck of the bottle so that the neck is disposed between the cylinder and the cover; and 
 a seal tightening section that encourages a water tight seal between the cap and the water bottle, the seal tightening section including
 a flexible neck sleeve that engages the neck and, when attached, extends both outwardly and away from the neck toward a body of the bottle, a portion of the sleeve extending beyond the cover, and 
 a collar that engages an exterior of the cover and selectively engages at least a part of the portion of the sleeve beyond the cover, pressing the engaged part of the portion of the sleeve toward the neck, 
 
 wherein, when the cylinder is inserted into the water bottle and the cover is fit around the cylinder such that the flanges are in contact, the filter is disposed only in the bottle, a portion of the neck is disposed between the cap and the cover, and the cap and cover cooperate to permit only filtered water to flow out of the bottle into a cooler.
